Respuesta :

Answer:

Scalar quantity

Explanation:

Scalar quantities are measurements that consist of only a magnitude which is measured in numbers only. For example speed is a magnitude because it measures how fast something is going.

Vector quantities are measurements that include a magnitude and direction which means there is a number measurement and a direction associated with that measurement. For example, velocity is a vector quantity because there is a measurement of speed, and it also includes the direction of the speed.
